Pulmonary rehabilitation is a cornerstone of management for patients after lung transplantation (LT), but the benefits of inspiratory muscle training (IMT) after LT in children are unclear. Therefore, we examined whether IMT can improve respiratory function and dyspnoea in a paediatric patient after LT.The patient was a 13-year-old boy who underwent double LT. However, mild physical activity such as walking triggered dyspnoea for the patient. The patient underwent IMT with the intensity of approximately 30% of his maximal inspiratory pressure (MIP) for 2 months.The patient’s MIP was increased by approximately 60% after 2 months, and his forced vital capacity as a percent of the predicted normal value increased from 74.6% to 83.4%, with improvement of dyspnoea.IMT may help improve dyspnoea after LT in children with respiratory muscle weakness and a decline in respiratory function.
